Sedum sieboldii

Soil: Average, dry to medium moisture, well-drained soils. Thrives in sandy to gravelly soils of moderate to low fertility. Needs sharp soil drainage to perform well.
Light: Full sun -- Tolerates some light part shade in hot summer climates, but will produce weak floppy growth when grown in too much shade.
Water: Dry to medium -- Tolerates drought once established, but should receive watering when conditions are hot and dry.
Spacing: 12" - 18"
Fertilizing: A handful of all-purpose granular fertilizer sprinkled on the soil each spring is generally all that is needed. If growing in rich soil, it should only be fertilized every other year. Dry granular fertilizers must be watered into the soil.
Winterizing: Dried flower heads of many varieties remain attractive in winter, whether left standing in the garden or brought indoors. Remove the debris (such as the remains of showy Sedums) from under and around your plants in the late fall, and continue to remove any debris as it accumulates. Small animals and bugs may take home in accumulated debris during cold weather. Does not need mulch in the winter.
Maintenance & pruning: Mature plants may require staking. Stop watering and fertilizing in the fall, and do not do so during the winter as well. Return to watering and fertilizing in the spring when new growth appears. Throughout the spring and summer, divisions and cuttings root readily.
